MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511116679 A) filed by Graphic Era, Dehradun, Uttarakhand, on Nov. 25, 2025, for 'a system and method for switching angle determination utilizing the coati optimisation algorithm in multilevel inverters.'
Inventor(s) include Dr. Bheem Pratap; and Khushboo Bharti.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The invention provides a system and method in the technical field of power electronics for determining switching angles in multilevel inverters using a Coati Optimisation Algorithm (COA) implemented in a digital processing unit. The system comprises a plurality of DC voltage sources (e.g., Vi1, Vi2, ..., Vin) connected in a staircase network, controlled semiconductor switches (e.g., SW1, SW2, ..., SWn) including a lower switching network and an H-bridge inverter stage (e.g., SW4, SW5, SW6, SW7), and a diode array (e.g., Di1, Di2, ..., Din) ensuring unidirectional current. An integration and control unit coordinates real-time switching based on Fourier series analysis and harmonic elimination criteria, making the invention suitable for applications in smart grids, renewable energy systems, and electric vehicle propulsion."
